# webView(_:createWebViewModalDialogWith:)

Creates a modal window containing a web view that loads the specified request.

```
optional func webView(_ sender: WebView!, createWebViewModalDialogWith request: URLRequest!) -> WebView!
```

## Parameters

`sender`

The web view that sent the message.

`request`

The request to load.

## Return Value

The web view that is loading the specified request.

## Discussion

This method is invoked when JavaScript calls `window.showModalDialog`. It should create a new modal window containing the web view and initially hide the window. The [`webViewRunModal(_:)`](/documentation/WebKit/WebUIDelegate/webViewRunModal(_:)) message is sent to the delegate to display the web view.
